Airlink 101 USB Wireless on Ubuntu 9.10


Howdy All,

So I recently obtained a USB wifi card, an Airlink 101 USB device. When I attach it to my Ubuntu system it is recognized by the network manager and it can see my wifi network - however it is unable to connect. When I enter the passcode for my wifi it spins trying to connect and then spits it back to me telling me I need to reenter the password after a few moments - I am 100% sure the password is correct. I tried the device on two different Ubuntu systems (one 32bit and one 64bit) and achieved the same results on each.

I can confirm the wifi itself works as I am typing from my laptop connected to it as we speak...

I think I've gained some insight into why the Wireless card does not connect properly - for some reason when I do an lsusb it lists the card as an atheros device even though it is a ralink chipset... Could this be causing the kernel to be using the wrong driver for the card? If so how do I go about telling my system that it is actually a different card than has been automatically recognized?

Regards,
~Jeff

Atheros/Ralink is related.
Post your lsusb to see your card and then lsmod to see the module that is loaded for it.
A little google will tell you wich driver to use for that card.

Solution involves blacklisting certain kernel modules for the ra2870 and installing the drivers from ralinktech.com as described here

Cheers!

I was just looking at your post... i noticed you are running an atheros adapter (most likely came as "features" on your laptop aka

Bus 001 Device 003: ID 14b2:3c27 Atheros Communications Inc

I had incredible trouble with this little jerk running windows 7 .... i finally had to upgrade from older Airlink equipment to the newest. the router now accepts the atheros adapter and i am running usb's on the other desktops.
